With the above said, assuming you have a neutral in your box, it's fairly easy to turn any smart switch into something that can control smart bulbs. Inside the box, you need to tie the line and load together and connect that to the line side of your smart switch. For the load of the smart switch, you'll cap that end. Then you just wire everything else like normal (ground to ground, neutral to neutral). What this wiring setup does is provide always on power to the smart bulbs and power to your smart switch. Then I use Hubitat and [RELEASE] Switch Bindings to connect everything together.
The advantage to Zooz and Inovelli is you do not need to tie the line and load together. Instead, you wire up the smart switch as normal and disable the internal relay (which in turn just makes the smart switch a button controller).
As for everything else, Hubitat serves as my automation controller with Google Home as our voice. I only share the smart bulbs to Google since if I turn on the bulbs, Hubitat will automatically turn on the switch to keep them synced.
